Perhaps never before has the Czech Republic been so divided over a piece of architecture. The winning proposal for a new National Library in Prague, which is supposed to be built in Letna, in the Prague 7 district, not far from the Castle, is a source of major controversy in the country.

The purple-and-yellow building proposal (see photo) has been designed by Jan Kaplicky, an architect of the London architecture firm Future Systems. Yes, it is an extremely bold design, for a city known for its Gothic and Baroque architecture.

People call it all kinds of things…octopus, jellyfish, blob, phlegm are among the nicer ones. I personally like it. But I like cities that mix and match their architecture, like New York.
